The argument made was this – Keane may have been a brilliant player and captain for Manchester United, but he is, to borrow a phrase from Noel Gallagher, a fork in a world full of soup.

Too harsh for modern football, where players need constructive criticism rather than a verbal assault to motivate them.

It is wrong because if that was all Keane had spent the past five years doing, he would not have lasted five months as Martin O’Neill’s assistant. There is a role Keane plays, fuelled by his successful television career, that he has mastered – a sharp-tongued critic of football, dripping in sarcasm and pithy observations, delivered with an array of pursed lips, glares and eye rolls.

And then there is the Keane who has worked with O’Neill. Loyal, insightful, bristling with positive energy, a motivational force.

The 47-year-old is a little softer around the edges.

Until that leaked bust-up with Arter and Walters, Keane’s rehabilitation as a coach was going well. There was a perception he had changed.

Still able to command respect, but no longer the confrontational, overly demanding figure who failed so spectacularly at Ipswich Town.

But as things unravel with Ireland, as the criticism grows stronger and calls for their removal louder, Keane has a choice to make.

Ireland will try to regroup after a woeful 2018 ahead of the European Championship qualification campaign in March.

O’Neill has vowed to carry on, but there is a chance he could be tempted away.

There will be offers. O’Neill has been approached several times by English clubs seeking new managers, most recently Stoke City this year, but turned them down. He may not have the same resolve next time.

His name remains above the door, but like a pub without beer, something fundamental is missing. Ireland are no longer playing like an O’Neill team.

His achievements, guiding Ireland to the knockout stage of the Euros for the first time, reaching a World Cup play-off with a poor team lacking a regular goalscorer, are forgotten. Such is the nature of management, when results go bad, but his work has always seemed to be rated more highly on this side of the Irish Sea.

The one stain on O’Neill’s reputation, after so many years of success with Wycombe, Leicester City, Celtic and Aston Villa, is his sacking at Sunderland.

Hardly career blemishing, when so many others also failed or got out before they could.

Keane was not one of them. His work at Sunderland should not be ignored; taking a team bottom of the Championship, promoted as champions and keeping them in the Premier League. He galvanised a football club and a city.

As bad as his time at Ipswich was, an experience that bruised because of the mistakes he knows he made, Keane should not be written off, especially if a club needs a spark.

If O’Neill leaves Ireland, there is a chance Keane will merely go with him, that he will carry on as an assistant. He enjoys it, but also because he has become so close to O’Neill.

Yet, it feels like Keane has unfinished business as a manager, that there is a club out there that needs someone like him to grab a team by the scruff of the neck and drag it upwards.

The question is, does Keane want to put himself in that position again? Is he willing to leave himself open to accusations he failed? Or is he just another outstanding player who does not need the hassle, when he can sit in a television studio and earn just as much?

Good weekend for...

Scotland

An underwhelming appointment for many given he was perceived to have failed the first time, Alex McLeish has wrestled with many problems since returning to the role. Scotland have spent the best part of two decades trying to come to terms with their decline, but the 4-0 away win in Albania means they will finish top of their Nations League group and secure a Euros play-off place if they beat Isreal.

Bad weekend for...

Ryan Giggs

Even with Gareth Bale, Wales were unable to get the result against Denmark that would have enabled them to win their group. It shows how tough the challenges ahead will be. There have been lots of positives for Giggs as he shapes a new young team, but it will still be a big ask for them to qualify for the 2020 European Championships. If they do not, Giggs will have failed to live up to expectations and that will bring criticism.
